CAR-DUMPING APPARATUS.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed January 2, 1913. Serial No. 739,838.

To all whom it may concern.'

Be it known that I, GEORGE H. MUELLER, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Car-Dumping Apparatus,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to car-dumping apparatus of the type in which afixed continuous track is provided, the cars being tilted into inclineddumping position by moving over a short sharply inclined section vofthat track.

The principal object of the invention is to provide an improvedmechanism for temporarily holding the cars in dumping position on theinclined track section.

Another object is to `provide a track having certain improved structuralfeatures.

Still further objects will be apparent from the following specificationand claims.

0f the drawings which illustrate one embodiment of my invention Figure 1-is a side elevation. Fig. 2 is a plan view. Fig. 3 is a fragmentarycross sectional view taken along the line 3-8 of Fig. 2.

Referring to the drawings, 1 represents the main feed track along whichcars move toward the dump, and 1 represents the discharge track forreceiving the cars after dumping.

2, 2, and 8, 3, are special rails which are preferably steel castings.The wheel-engaging surface of each rail 8 is formed in two sections atan angle to each other, the upper sections 3a alining with the rails ofthe feed track 1 and the lower inclined sections 3h alining with therails 2, which in turn aline with the rails of the discharge track la.The upper parts of the rails 2 are preferably curvedupward so as to forma continuous smooth rail-engaging surface with the lower sections of therails 3, the rails 2 being connected with'the rails 3 by means of bolts.The rails 2 and 3 are preferably provided at 1, 5, and 6 with bracketsor pedestals by means of which they can be connected to the frameworkupon which the dump as a whole is supported. Cross connections betweenthe rails are provided at 7, 8, and 9, each connection consisting of aspacer tube or pipe and a tie-bolt extending through thel pipe andthrough suitable apertures in the rai s.

It will be observed that the construction which I have describedprovides three track sections. The upper of these track sectionsconsists of the parts 1 and 3a and is horizontal or-only slightlyinclined. Another of these track sections consists of the parts 1a and2, and is also horizontal or only slightly inclined. Between these twosections there is the sharply inclined section 3b which connects theother two Sections. The car to be dumped must first move along the upperhorizontal section, then into dumping position on the sharply inclinedsection, and subsequently along the lower horizontal section away fromdumping position.

In order that the car may be retained in its inclined dumping positionlong enough to permit the contents to be discharged, means are providedfor engaging the car and holding it in position on the inclined section.rhe means shown in the drawings comprises the two hornsrlO, 10 which aremounted upon the transverse rotatable shaft 11. This shaft is mounted inbearings 12, 12 which are secured to the rails 3, 3. Each of the hornspreferably comprises two parts, one of which is a casting keyed orotherwise rigidly connected with the shaft and the other of which is acurved bar of steel or wrought iron riveted to the casting. One of thehorns 10 is provided with or has formed as an integral part thereof anarm or counterweight 13. This counterweight serves to normally hold thehorns in the position indicated by dotted lines in Fig. 1.

14; is a rock shaft mounted in suitable bearings 15, 15a secured to therails 3, 3. At the end of the rock shaft 14 which is adjacent thecounterweight I provide a stop or dog 16 which can engage a suitablecurved surface 17 of the varm or counterweight 13. A hand lever 18 issecured to the rock shaft 14, preferably at the other eii'd thereof, andby means of this Vhand lever mounted on the shaft 14.

the rock shaft can be moved to throw the dog into or out of position toengage the arm 13. It will be clear that when the arm is engaged by thedog, the horns 10, 10, will be stopped in the positions indicated byfull lines in Fig. 1, the car thus being held in dumping position. lhenthe dog is moved to release the arm the horns can move downward andpermit the car to pass onward along the track. A stop 13a limits themovement of the arm 13 and of the horns 10, 10. As shown in Fig. 3, thebearing 15a, which is adjacent the dog, has aV stop 19 in the sidetoward the dog,'and the dog is provided with a shoulder 20 adapted toengage the stop. In this way there is provided positive means forlimiting the forward movement of the dog. For nor mally holding the dogin its forward operative position, with the shoulder engaging the stop,I provide a horizontal arm 21 upon which is an adjustable counterweight22. The arm 21 is secured to the shaft 14 by means of a bracket 23. Itwill be clearthat theV counterweight 22 acts to move the dog forward andthat it can be moved backward out of operative position only when theoperator actuates the lever 18. At the end of the shaft opposite to thaton which the counter-weighted arm 13 is located I provide a brake wheel24 around which passes a brake band 25. VOne -end of the brake band 25is connected to links 26, 26 which are loosely mounted on the rock shaft14; The other end of the brake band is connected to a lever 27 which isrotatably Secured to this lever 27 is a horizontal arm 28 upon which isadjustably mounted a counterweight 29. This counterweight serves to movethe lever 27 in the direction to tension the brake band. For lifting thecounterweight to release the brake band, there is provided the smallrock shaft 30 which is connected by means of the arm 31 and the rod 32with a hand lever 33 loosely mounted on the rock shaft 14. An arm 34;and a link 35 connect the rock shaft 30 with the end of the weight arm28. By means of this construction, the operator by moving the hand iever33 can lift the weight to release the brake.

When a car to be dumped approaches the dumping apparatus, its wheelswill rst engage the horns 10, 10, which are initially in the positionindicated by dotted lines in Fig. 1. The brake will be automaticallyapplied by means of the counterweight 29 and v Vthe dog 16. will be heldin operative position by means of the counterweight'22. The car,therefore, moves downward into inclined dumping position on the sections3b ofthe rails 3,it's downward movement being first resisted andretardedby means of the brake and then stopped by the engagement ofthe dog 16with the arm 13. The doorof the turn the horns to the initial operativeposicar can be opened either manually or by any desired mechanism, andafter dumping, the car is released by the operators 1moving the lever 18to disengage the dog 16 from the arm 13. The weight of the car thenpushes the horns downward out of the path of the wheels and the car isfree to move onward. If desired, inorder to permit the car to moveonward more easily,'the operator at the same time that he releases thedog 16 can also loosen the brake. In any event, after the car has beenallowed to pass onward, the operator releases the brake and permits thecounterweighted arm 13 to retion. The apparatus is then ready foranother car. f Y t In my co-pending application for dum-p ing apparatus,Ser. No. 639,306, filed VJuly 19, 1911, I have shown and described a cardunipi-ng lapparatus in Amany respects similar to that herein disclosed.However the apparatus here shown has a number of important features notpresent inthe earlier mechanism. Gne of the advantages of this presentmechanism is that two Vcontrolling levers are provided, one for the dog16 and another for the brake. In the earlier mechanism the brake and thedog were controlled by the same lever, it being on this accountimpossible to control one ofvthem independently of the other.l lVith thetwo-lever construction itv is possible for the operator toV releasethedog and by keeping hshand on the other leverv tension the brake bandjust suh'iciently to hold the horns against moving upward too soon. Itwill be observed that the horns must be held in their lower positionuntil after the rear wheels of the car have passedr In theearlierconstruction 105 it was found necessary to provide a supplementalbrake for thus holding the horns. In the present construction thissupplemental brake is done away with. Another feature of importanceV inthe present construc- 110 tion is the counterweight 22 for holding thedog 16 in operative position. With the independent controlling lever itwould be possible without this counterweight or its equivalent for theoperator to carelessly 115 leave the dog in inoperative position as acarentered the dump. Under these conditions the car would not be stoppedbut would be permitted to move over the dump without its contents beingdischarged.

The formationA of the rails 2, 2, and 3, F3, of cast steel makes itpossible for these parts of the tra-ck to be more securely supported.

`It will also be observedthat the rails 3,3,

quickly set up without the `necessity for at- 13o.'
